Do this mathematics task /b faggots.

A raft travels from village A to village B in 32 hours, but a ship travels from village A to village B in 4 hours. Calculate how much time will it take for the ship to travel back from village B to village A
>>
>>>/sci/
>>
answer: no solution

proof: ships only travel from village a to village b as stated in problem

OP's friend here. Please leave your solving scheme too, if you can.
>>
>>681960302
4 hours
>>
>>681960302
is it a lake or a river or what? current may be a factor here
>>
what are the current weather conditions also, this would also play a huge factor.

My mistake. Did not include that it is a river.
>>
>>681961395
could take forever if the ships engine isnt powerful enough
do they even have enough fuel?
>>
>>681961179
My mistake. Forgot to include that it is a river.
>>
>>681960302

the answer is 3.55555... hours. i won't leave my solving scheme because i'm not doing your high school homework for you.
>>
>>681961603

obviously this is assuming that the only factors at play are the speed of the ship and the speed of the water.
>>
>>681961645
how fast is the water?
>>
Well if its a river its traveling against the current back, so it would take almost double the time....idk..maybe 8 hours
>>
>>681962032

you can't figure that out from the information in the problem. you don't have to.

32/4=8
4/8=0,5
then remove the force of the water is pushing the boat on and ad the resistance
0,5*10=5
so five hours
I could be compleatly fucking wrong though
>>
the same amount of time it takes you to quit being a faggot. it never gets there.
>>
o m f g this thread ahahahah
>>
Speed of river 1/32 units/hour
Speed of ship: 1/4 - 1/32 units/hour = 7/32 units/hour
Speed of boat on the way back: 7/32 - 1/32 units/hour = 6/32 = 3/16 units/hour
V=s/t, t=s/v,
Time to get back: 16/3= 5,333 hours.
>>
>>681962659

so you're saying that the boat makes 4 hour time against the current, and it takes longer when it's going with the current? i think you done messed up
>>
>>681962982

>>681963088

this guy did it too lol. check your signs.
>>
Current is going from a to b. So the boar takes longer from b to a.

There isn't anything about the direction of the current.
>>
>>681963495
Probably from a to b. (Cause the raft is going from a to b)

The answer is 2
>>
>>681960302
if we assume the raft is unpowered and the distance is 320 miles, the river is flowing from a to b at 32mph. and the ship is moving at 80 mph from a to b. subtract 32 from 80 and get 48. 48mph is the ships max speed through the water. so going from b to a the ship would only be going 16mph if you account for the flow of the river. so it would take the ship 64 hours to go from b to a or Double the time the raft takes to float from a to b.
>>
>>681964844
If s=320, v=s/t=320miles/32h= 0.1mph
>>
>>681963088
Check the question again.
>>
>>681965213
nigger I give no fucks to your symbols. this is dead reckoning. in the end the answer is still the same because my error was carried through the proof. the ship takes 2x as long to go b to a as the time it takes the raft to float from a to b
